Attic Insulation in Key Largo,

Tavernier & Islamorada

Why Attic Insulation Matters in the Upper Keys

In the Keys, your AC runs nearly year-round, and your attic takes the brunt of the sun every day. Without enough insulation, that heat comes down through your ceiling and your AC has to work harder to keep up.

Many Upper Keys homes are older than most in South Florida: the median home in Key Largo was built in 1983. And close to 40% of Key Largo homes sit vacant at any given time, many of them second homes that keep the AC running while no one’s there. Whether you live here full-time or part of the year, an attic with the right insulation keeps that AC from working harder than it has to.

Frequently Asked Questions: Attic Insulation in the Upper Keys

What R-value do homes in the Florida Keys need?

The Keys are in South Florida’s climate zone, where ENERGY STAR recommends R-30 for attics. That’s what we install.

My Keys home is a second home. Is insulation still worth it?

Yes. Your AC keeps running while the house is empty to hold back heat and humidity. Better attic insulation means less heat coming in, so the system works less while you’re away.

Do you install attic insulation in Islamorada and Ocean Reef?

Yes. Our Upper Keys team serves Key Largo, Tavernier, Islamorada, Plantation Key and Ocean Reef.

Do I need to remove my old insulation first?

In most homes, no. New blown-in insulation goes on top of what’s already there.
